VSCode autocomplete doesn't work for mix-created projects

satoru

I’ve installed vscode-elixir and autocomplete works as expected when I’m editing single files.

But when I create projects with mix new, the autocomple doesn’t work.

It’s quite weird, when I run code something.ex in the root of the project directory, autocomplete works. But it doesn’t work for mix.exs in the same directory.

Hi @satoru,

The community has rallied behind the ElixirLS extension, which is the most actively maintained. Perhaps see if it serves your purpose?

I’ve tried ElixirLS but it crashes every time with errors like:

[Error - 5:12:50 PM] Connection to server got closed. Server will not be restarted.
[Error - 5:12:50 PM] Request textDocument/documentSymbol failed.

Could you post your setup (OS, versions of Elixir, VS Code, ElixirLS, etc)?

OS: macOS
Started ElixirLS v0.4.0
Elixir version: “1.10.3 (compiled with Erlang/OTP 22)”
Erlang version: "23

It seems that it’s two textDocument/xxx requests that are failing.
I’ve Googled some of the error messages but find nothing useful.
When I googled “ElixirLS crash” I saw someone mentioned that it might be caused by the dependency to something called “dialyzer”. But ElixirLS still crashed even after I disabled “dialyzer” in the configuration.

Thanks for pasting the ‘ElxirLS Copy Debug info’ output.

mix compile works? The project compiles correctly from the command line?

I don’t know what’s happening but after I disabled ElixirLS and reinstall vscode-elixir, autocomplete is working again even for mix projects.

I wouldn’t expect vscode-elixir to work properly on anything newer than elixir 1.5. it uses an over 3 years old elixir_sense dependancy. A lot has changed in elixir internals since then (especially in 1.7 and 1.10).

@satoru Could you post a more complete error log from ElixirLS?. Also how did you install erlang and elixir?
Please note that for ElixirLS to work other extensions may need to be disabled.

Thanks for replying.

My Erlang and Elixir are installed with homebrew.

I prefer you to install erlang and elixir using asdf https://github.com/asdf-vm/asdf-elixir and then uninstall ElixirLS and reinstall it. I hop[e this will fix your issue.

Thanks. It looks like your project dir is set to nil for some reason.
It’s crashing in line

Path.join([project_dir, ".elixir_ls", ".gitignore"])

Try setting it to . in extension settings
